Do you have your copy yet?

You could spend years wandering this forum and not learn as much as what's in the book. Explains adaptation and programming when you hit ruts, basic physiology and much more. Explains the real difference between novice, intermediate and advanced trainees (which has nothing to do with strength BTW).
